To ALL wHoM 1T MAY'CONCE'RN:

Beit known thatl, ANDREW'HARTMAN, of Canton, in the county of Stark, and State of Ohio, have'invented l new and useful Improvements in Railroad-Gates; and I do hereby declare that/the following isa full, clear,

and exact-description of my invention,rei`ercncc being had to the accompanying drawings, forming a part of this specilication, and to vthe letters of reference marked thereon, in which drawings Figure 1 is a. side view .of my improved gates. l Figure 2 is'a plan of the same. I Figure 3 is a detached side view of the rod, spring, Sto., which close the gates.

' The nature of my invention consists inthe novel construction and arrangement of several rods,levers, springs, sockets, &c.,.as hereinafter set forth, in such a manner that the flanges of the cars or locomotive, by

acting on the lever on the side of th`e'rail, shall cause the gates to turn down into a lat position, so as to allow the train to pass over them; also inthe peculiar arrangement of the catches thathold the gates down while the train'is passing, and which,'by the action of a leveriattached to the rear car oi' the train, release the gates as" soon 'as the train' has passed, when the gates assume their original vertical position.

To enable-others skilledinthe art to make and use my invention, I will proceed to describe* its construc-l tion and operation.

The gates C C' areof iron or other suitable material, being made by forming the slats pp' into the hori zontal bars O 0'; These horizontal bars maypass through the rails M, as shown, or have a box attached to the bottom of the rail, beingin either case free to rotate. The.` levers A A' are placed at the side of the rail, the

lhollow of the rail being 'lled by a suitable-shaped piece, wood or iron,` and have the bolts a a' as axles, one end of the bolts-a d being in the rail, and the` other end in the irons b b. The levers A A have their ends c c made'in an oblique wedge-shape, so that when a wheel Vconnes to the lever A, and rst strikes the end, c, the flange of the wheelfconres between the rail M and lever A, and slides'the lever A along on the bolt a, while a wheel approaching in the oppositedirection, the ila-nge runs on the lever A', and forces it down, instead of slid-ry ing it on the bolt for a -re'ason hereafter shown. ,The rock-shafts B B are hung in the boxes e e'e' e', which are fastened lin irons which pass from the tie's N1 to N2, as shown. The arms D D of'theseV rock-shafts are directly under the ends c cof the levers A A', and have a hook from the end c e', 'passing through an eye in their ends. The rods F'F areattached to the arms E E', and on the opposite ends 'ot` these rods, on the spiral springs g g', which vare arranged in the boxes Gr-G, as shown. The rods H I-I'are attached to the boxesG G', and pass through the slides I I', and have nuts, w w', on their other ends, as shown, the rods being made so as'to slide through the slides I I', so that one side of this automatic arrangement shall not interfere-,with the free action of the other side. The rods JJ', having the slides I I at the ends, are attached to the arms g g on the horizon tal bars O O" ofthe gate C C'. The rod l is attached to the arm 7c of the gate C, and on its othervend is the spiralspring s, which is enclosed Vin the box m, which box is secured to the board n oil the ties N1 'N z. The springs d Zkeep the levers A A' vup to their places, and the springs a: :t keep the levers A A' pressed against the rail M, as shown. ,The lever K is attached to two arnis, z'z", on'.the bars O O', lsaidar'ms being either en the top or bottom of the bars 00', the object being to cause both gates to riseand fall simultaneously. The catches L L are hung on the-rods ri", being free to'rotate on said rods. The rods'r r" are'fattached'at one end to the .irons tt' on the ties N3 N4, and pass through aA slotted hole in the bars v e', and are attached` at their other ends i to the rods u a', which rods are attached to the rods H H', as 'shown in iig.V 2. The bars ff' are placed at such l a distance fromthe horizontal bars O 0', and between two adjacent slats of the gates, as that when the gates are rotated into aat position, these bars ff' are caught by the catches L or L', and the gates are'held down.

The'operation of these gates is as follows :v A ltrainapproaching the gates, and iirstcomingon to the lever A, depresses said lever, andcuuses a rotation ofthe rockfshaft B, which acts on the parts F,'G,'H, I, J, and4 by-thus drawing on the army, causes the gate C to rotate. into a'lat position, and ,als the gates and C', are connected by the bar K,'as before shown,"both gates will be-caused to assume the saine,iiatfposition.l .The spring q preventslthe motion caused by the action .of the lever Afrom being`too'rapidlyfcommunicated tothe gates. The rod u being attached tothe rodH, draws back the lever r, on which is hung they catch and the bottom Df Said Catch Striking against the stop IL, causes thecateli .L to be turnedback, so as to prevent its catehingthe bal-f when the gates come into a' Hat position. The slides I allowing the rod H toslicle through it, there will be no action ofthe lever r', on which is hung the catch L', consequently, when the gates assume a ilat position, the catchL catches on the bang", and the gates are held `down until the last ear passes, when a bar, to be attachedto the rear end of the last car, strikes tl1e`t op of the catch L, and throws it back, thus releasing th`e gates, which, by the action of the rod Z ancl'spring s, attachedto the arm c, causes the gates to assume their original position. The flanges of the car-wheel pass between the lever A and the rail M, causingtlie lever to slide along the rod a, -bnt causing no action of the rock-shaft' B', The ac'tionof a train, when coming towards the gates, and rst coming on to the lever A, is precisely analogous to that just described, and vneeol not be particularly specified. 'In this manner I arrange the gates, with the machinery as shown, at any point'where a. highway crosses the railroad, the whole forming a self-operating apparatus, and preventing cattle or stock of any kind from coming'on to the track, `excepting at the point Where the highway crosses the railivay-track.

IdoA not claim the gates C C as' my invention, but What I lo claimV as my invention, and desire to secure by Letters Patent, is

1. The combination of the rods F, H, JA', box G, spring ),'sliile I, and nut w, the several parts being arranged in'the manner and for the purpose herein specified. Y

l 2. The combination of the lever A, and the springs d andl .f-v, the several parts being arranged as and for the purpose herein set forth. l, I v

8. The combination of the gates O O, rods K and Z, arms z'z' 7c, springs, and box m,thc several parts being arranged in the manner'and for the purpose specied.

4. The peculiar arrangement of the irons t t', levers 1'1"', catches L L', slotted irons 111/, rods u u', vand stops h 7L', the several parts being used as `and for the purpose herein` specified.

5.' The peculiar arrangement andvcombiuation of thcgates, levers, rock-shafts, rods,springs, boxes, slides, catches, and slotted irons, as lherein shown, the whole i'oiu'ning a self-operating. apparatus, in the manner and forv the purpose herein specified.

Ars/evidence that I 'claim' the foregoing, I have hereunto set my hand. in presence of two witnesses.

I ANDREW HARTMAN.
